in generally you could do this in several draft, one were you put high level descriptions, and one where you fill in the details, eg put actual quotes from transcripts in audio column, and clip names/screenshots in video column.

eg a first draft could like this:

Structure

Audio

Video

Intro

Contributor introduces himself

Some kind of Opening shot

And this would be a more detailed draft.

Structure

Audio

Video

Intro

P: My Name is...

Opening shot of headquater

Example: Two column script and 3 act structure

In previous sections we have seen the three act structure. Here is an example of how you work it into a template to help the thinking over the events of your story, in a two column script.

Structure: simplified

You can also go for a simple structure, eg just one act. Or if drawing on previous paper-edit process, and working on shorter piece could go for something like this:

introduction

theme/topic 1

theme/topic 2

theme/topic 3

conclusion

And some times that would be more then enough.

However as mentioned above this is not a formula, the structure of your story should serve it's content. If you want to use a different structure you can read "The Seven Basic Plots" book and work from one of those, or use it for inspiration as a starting point and make your own.

Regardless of what you chose for the structure. Remember to consider McKee's writing from the inside out as an essential story crafting technique to make the most of this step. And refer back to the previous paper-edit process to see how that would apply.

Last but not least remember that is once you know the principles that you can master the art.
